So print_insn_arm() calls arm_read_memory_func() with length==2, and info->flags == INSN_ARM_BE32, and the assert is false. + +If I remove the assert, execution continues OK. + +With the assert, I get the error message from the assert, and qemu then stalls. + +Can you confirm the assert can be removed?
